PAPER-RAG ENGINE.

Specification of Letters Patent No. 27,167, dated February 14, 1860.

To all whom it may concern:

Be it known that I, JOSEPH STORM, of Voonsocket, in the county of Providence and State of Rhode Island, have invented anew and Improved Rag-Engine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming apart of this specification, in which- Figure 1 represents a longitudinal vertical section of this invention. Fig. 2 is a horizontal section of the same.

Similar letters in both figures refer to corresponding parts.

This invention relates to certain improvements in that class of rag engines, in which a rotary drum is employed to keep up a constant supply of rags to a revolving cutter cylinder operating against stationary knives.

My improvement consists, first, in the employment of a conductor attached to the stationary knives for the purpose of regulating the supply of rags to the cutters.

To enable those skilled in the art to make and use my invention I will proceed to describe it.

A represents a frame of cast iron or any other suitable material connected and steadied by cross bars, a, which are secured to the side pieces of the frame by screws, 7). In this frame and supported by 'trunnions, o, is the drum, B, furnished with a cover, C, that serves to introduce the rags. The trunnions, c, of the drum are hollow, and they run on friction rollers, (Z, so as to enable it to work with as little power as possible.

In the inside of the drum, B, and secured to a shaft, 6, is the cylinder, D, carrying a series of cutters, 7, that are fastened to the same by rings, g, or in any other suitable manner. The shaft, 6, of the cutter cylinder extends through the hollow trunnions, 0, and it has its bearings in journal boxes, E, that are secured to the sides of the frame A.

F are the stationary knives, four in numher, which are secured to a bar, k, that rests on inclined platforms, 2', secured to the journal boxes, E, on the sides of the frame, A. The ends of the box, h, are furnished with slots, 7', to receive the set screws, 70, and the ends of the platforms, i, are turned up to form lugs, Z, into which the screws, m, are fitted, and these screws act on springs, 0, which are firmly secured to the bar, h. If it is now desired to bring the knives, F, into the proper relation with the cutter cylinder, D, the screws, k, are unscrewed and the knives are adjusted so that they nearly touch the cutters on the cylinder and that the cutting edges of the knlves are perfectly parallel with the cutting edges of the cutters. The set screws, 72, are screwed up now, and the screws, m, are so adjusted that they touch slightly the springs, 0. By opening the set screws, 70, the knives are now forced toward the cutters with a gentle pressure of equal force on both sides, and, at the same time, the knives are allowed to give way in case some hard and injurious substance, such as nails, should be mixed up with the rags. The rags which are put into the drum through the door, C, are taken up by projecting slats, G, that are secured to the inside of the drum, and a conductor, H, serves to bring the rags as they drop down from the slats, G, to the cutters. In passing through between the cutters, the rags are cut up into pieces and by pursuing this operation for a certain length of time, the whole contents of the drum is reduced to the required fineness.

The drum, B, as well as the cutter cylin-- der, D, receive their motion from the driving shaft, I, which is furnished with two pulleys, J, to correspond in their posi tion to the pulleys, J, on the ends of the shaft, 0, of the cutter cylinder, and a pinion, K, by means of an intermediate gearing, L M, and by the toothed rim, N, on the side of the drum, serves to impart motion to the latter. The strain exerted by the belts from the pulleys, J, on the shaft, 6, is equal on both sides so that no unequal wear can take place on the journals or journal boxes of said shaft, and that the proper position of the cutter cylinder in regard to the knives is not disturbed.

By this machine the rags are cut up to the required fineness in a very short time,

and it needs no attention except for chargknives, F, arranged substantially as and for ing and discharging. d d the purpose specified.

What I c aim as new an esire to secure by Letters Patent, is JOSEPH STORM 5 Theemployrnent of the conductor, H, in Witnesses:

combination W1th the rotary drum, B, the VANNORJE GREENE,

rotary cutter cylinder, D, and the stationary PAUL GREENE.
